Glacier Park International Airport (IATA: FCA, ICAO: KGPI, FAALID: GPI) is in Flathead County, Montana, six miles northeast of Kalispell.[1] The airport is owned and operated by the Flathead Municipal Airport Authority, a public agency created by the county in 1974.

The airport's ICAO code was KFCA, and most airlines still use that code for reservations purposes. Most U.S. airports use the same three-letter location identifier for the FAA and IATA, but Glacier Park International Airport is GPI to the FAA and FCA to the IATA (which assigned GPI to Guapi Airport in Colombia.)

In the year ending January 1, 2007 the airport had 51,925 aircraft operations, average 142 per day: 70% general aviation, 21% air taxi, 8% airline and 1% military. 159 aircraft were then based at this airport: 78% single-engine, 16% multi-engine and 3% jet and 3% helicopter.[1]

Delta operates mainline narrow-body jets and Delta Connection operates regional jets using CRJ and Embraer aircraft. Daily nonstop flights to Minneapolis/St. Paul and Salt Lake City are operated year-round by both Delta and its regional affiliate. This is supplemented by seasonal/summer service to Atlanta and Los Angeles on mainline aircraft.

United Express operates daily nonstop jet service to Denver year-round on CRJ aircraft. During summer, it operates seasonal nonstop jet service to Chicago[2] (six times a week) and San Francisco[3] (daily).
